| Abstract: | TiO 2/SiO 2 as a catalyst is prepared by adopting sol gel process to prepare SiO 2 colloid which is then recombinated with anatase type TiO 2 fine grains. Its outside appearance is observed by transmission electron microscope and its structure is characterized by infrared spectrum and X ray diffraction. Taking dichlorvos solution as the system, the catalytic performance is investigated and compared with that of the single anatase type TiO 2. As shown by the results, TiO 2/SiO 2 has a higher photocatalytic performance than that of TiO 2. |
